Characterization of the external limbus on corneoscleral topography with ultrawide-field optical coherence tomography

The limbus is the transition area between the cornea and the sclera. Demarcating the corneoscleral limbus is important for fitting scleral lenses. A scleral lens is a rigid contact lens that vaults over the cornea and the limbus, resting entirely on the conjunctival surface over the sclera. Scleral lenses are often fitted following a diagnostic approach in which an initial lens is chosen from a trial set and the lens parameters are refined by a trial-and-error process. The number of trials needed to find the best lens typically ranges between 1 and 8 lenses [1].
